I needed to get the list of my reports and what data source and dataset they use.
use ReportServer;
WITH XMLNAMESPACES ( DEFAULT ‘http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition’, ‘http://schemas.microsoft.com/SQLServer/reporting/reportdesigner’ AS rd )
SELECT distinct ReportName = name
,DataSetName = x.value(‘(@Name)[1]’, ‘VARCHAR(250)’)
,DataSourceName = x.value(‘(Query/DataSourceName)[1]’,’VARCHAR(250)’)
,CommandText = x.value(‘(Query/CommandText)[1]’,’VARCHAR(250)’)
FROM ( SELECT C.Name,CONVERT(XML,CONVERT(VARBINARY(MAX),C.Content)) AS reportXML
FROM ReportServer.dbo.Catalog C
WHERE C.Content is not null
AND C.Type = 2
) a
CROSS APPLY reportXML.nodes(‘/Report/DataSets/DataSet’) r ( x )
CROSS APPLY x.nodes(‘Fields/Field’) f(df)
ORDER BY name
Good Luck
